Radiation poisoning

material's low-energy gamma rays to be used in some cancer treatments while the alpha radiation emitted minimally effects the contaminated host (Wanless, A., 2011). Americium can be useful to humans, despite its radioactive state as it is used in testing devices such as fluid gauges, thickness measurements, and is also used in the production of domestic smoke detectors. Exposure to ingestion results in internal radiation and the material can then be transported through the circulatory system of…

Light is an electromagnetic radiation that can be detected by humans. Electromagnetic radiation happens in an extremely large range of wavelengths from gamma rays to radio waves. Within that spectrum the wavelengths visible to humans are few. Light is very difficult to define, in the sense that scientist have been arguing weather light is a particle or a wave. Many experiments have been done to proof weather light is a particle or a wave. The truth is that light sometimes acts as a wave and…

spectra because the atoms can absorb “very specific wavelengths from white light.” (Slater) 9. What is the Doppler Effect? Why is it important to astronomers? (Page 49 – 50) a. The Doppler Effect is the “apparent change in the wavelength of radiation due to the relative motion between the source and the observer along the line of sight.” (Slater) b. The Doppler Effect is important to astronomers because it gathers “basic information about the motions of planets, stars, and galaxies.”…

In 1905, independent Danish astronomer Ejnar Hertzsprung and American astronomer Henry Norris Russell gathered data of a star’s spectral type and there temperature. They plotted these data on graphs and discovered that many patterns emerged linking the mass of a star to its lifespan. From the noted trends and correlations they formed what is now known as the Hertzsprung Russell Diagram or commonly referred to as the HR Diagram. The HR Diagram is used as an important tool in the study of…

Prostate cancer is abnormal cell growth and tumor formation in male prostate gland, which is a part of male reproductive system. Prostate cancer is one of the most common cancer type affecting human male population around the world. Recently, over 1 million men from all over the world were diagnosed with prostate cancer where developed countries accounted for 70% of these cases [1]. According to the same report in year 2012 prostate cancer left estimated 0.3 million human male people dead…

According to Samuel S. Epstein, Cancer prevention expert and Prof. Emeritus at University of Illinois School of Public Health in Chicago as well as Founder/Chairman of the Cancer Prevention Coalition, “Of more than 100 radioactive chemicals in fallout, Sr-90 was the most feared. This radioactive fallout, as it is called, carries something that’s called strontium-90, which is the most dreadful poison in the world. For only one tablespoon equally shared by all the members of the human race could…

Uranium, which are found in soil and rock throughout the world. This radon then breaks down into solid radioactive elements which are called radon Progeny. This radon progeny can then attract to air particulates and if inhaled can give off high energy radiation which can damage the DNA inside the body’s cells. In comparison with Radon in outdoor air, humans confined air spaces, such as mines and buildings, are exposed to higher concentrations of radon. The levels…

Synthetic Dye Assignment Dye: Sunset Yellow FCF Caitlin Walker Sunset Yellow FCF, more commonly known as Yellow 6, is an orange azo dye3. This dye is petroleum-derived and its absorption is dependent on the pH. Minimum absorption occurs at 480 nm with a pH of 1 and maximum absorption occurs at 443 nm with a pH of 13. Sunset Yellow FCF is soluble in cold water2. Sunset Yellow FCF has the following structure (Figure 1). Sunset Yellow FCF is commonly used in food, cosmetics, and drugs. It is…

Daniel Hauser is a 13-year-old boy from Sleepy Eye, Minnesota. Daniel was diagnosed with Hodgkin’s disease in January 2009. Doctors stated that this type of cancer was highly curable, but if he did not get the proper treatment then he would most certainly not survive. The proper treatment according to the doctors was six rounds of chemotherapy. Daniel completed one round of chemotherapy in February. After that Daniel and his family refused to go through more rounds of chemotherapy and opted for…

The Atomic Bomb Lighting the Way for Radiation Protection Even though radiation has been around since the beginning of time there was little known about it. When x-rays were discovered in 1895, radiation research followed suit right after. With Germany under Hitler’s reign, the Nazis began separating uranium to form the first atomic bomb to control the world. The push for the United States to be the first with the atomic bomb began with this knowledge. With the help of several scientists…
